Description

FIELD OF THE INVENTION

The present invention relates in particular to securing the transport of ships on solid surfaces.

A favorite application concerns the shipbuilding industry and more particularly light craft both for tourism and for professionals.

BACKGROUND

In the latter area, many tourist vessels are known that can be positioned on a trailer in particular to be towed by a conventional land vehicle. In particular, for regulatory reasons, trailers must have a license plate holder and signaling elements (headlight, turn signal, reversing light, brake light, etc.). Usually this support is positioned on the trailer below the hull of the ship. Thus, said support can serve as an underride bar in particular to prevent pedestrians and / or both wheels from passing under the wheels of the trailer. Always known manner, these supports are retractable, and can not be removable according to the regulations

A similar problem also arises for amphibious vehicles capable of moving both in a liquid medium (mainly water) and on solid surfaces. In this configuration, the registration plate and the signaling elements are conventionally on a support which is below the hull. In this situation, this support is awkward when navigating in the water. In case of removability, this poses problems of sealing and storage of said support and does not allow to comply with the regulations and in particular to ensure the proper return to position of the safety system that is the underride bar.

Thus, it is desirable to develop and develop a system capable of responding to greater safety of the land transport of ships while limiting the disadvantages of this safety during navigation. The invention solves all or part of the disadvantages of current techniques.

SUMMARY OF THE INVENTION

One aspect of the invention relates in particular to a ship comprising a hull capable of being towed on a solid surface,

Advantageously, said vessel comprises an anti-embedding device configured to be movable between a first position in which the device is in function against backstop and a second position in which the device is not in function underrun.

This advantageous feature allows the ship to understand an underrun device that perfectly meets the safety of land transport of a ship and whose disadvantages relating to this device are limited.

Another aspect of the invention provides that the first position of the underrun device (20) is configured to be below the second position. This advantageous characteristic allows in particular the first position to be close to the ground, while the second position having a secondary function may be further from the ground than the first position. Thus, the range of secondary function is wider.

In an alternative embodiment of the invention, the arm 21 and the structure 22 are formed a monolithic part. The arm 21 can be made of different materials. In the preferred embodiment of the invention, the arm 21 is made with a tube including stainless metal. This preferred embodiment makes it possible in particular to have a good resistance to effort, while limiting the mass of the anti-recess device. In the first position of the underrun device, said arm 21 is oriented in a predominantly horizontal direction. In the second position of the underride device, the arm 21 is oriented in a predominantly vertical direction (see FIG. 1). The arm 21 may be straight. It may also have a curved shape as is the case in Figure 1. The form of the arm 21 described is not limiting, and other forms are of course possible.

Advantageously, the lower end of the arm 21 is connected to the shell 11 at a steering console 12 of the ship 10. The term "pilot console 12" refers to the part of the ship 10 that makes it possible to control in particular the direction and speed of the ship. 10. Preferably, the length of the arm 21 is greater than the length between the axis of rotation 23 and the bow 13 and / or the stern 14 of the hull 11 of the ship 10. This advantageous configuration allows in particular the arm 21 d reaching one end of the shell 11 and the structure 22 to protrude from the shell (Figure 1 for example) during the positioning of the underrun device 20 in its first position. In an alternative embodiment, the arm 21 is telescopic. Thus, it can quickly adjust to the desired length of the first and / or second positions.

In one embodiment of the invention, the arm may carry, over its length dimension of the signaling elements 25 especially for marine navigation and including navigation lights (port, starboard and anchor).

The structure 22

The structure 22 is advantageously made by stainless metal tubes. Of course, other materials can be used and this embodiment is not limiting. Advantageously, the structure 22 comprises a length dimension and a width dimension. Advantageously, the length dimension of the structure 22 is the dimension parallel to the longitudinal axis of the ship 11. The width dimension of the structure 22 as for it is parallel to the dimension in width of the ship 11.

Preferably, the structure 22 is configured to carry at least one support 24. The support meanwhile can carry the license plate 26 (for land vehicle) and / or the signaling elements 25. In another embodiment of the invention, the registration plate and / or the signaling elements 25 are carried directly by the structure 22. The signaling elements 25 may be signaling elements 25 for moving on the solid surfaces (dipped beam, reversing light , brake light etc.), but also navigation light signaling elements (port, starboard, inking). Unique signage can be used for both land and sea travel. For example, the maritime traffic lights may be positioned on one side of the signaling element, while the terrestrial traffic lights may be worn on the upper face of the signaling element.

In the preferred embodiment of the invention, the structure 22 is a frame whose length dimension is greater than or equal to the width dimension. In a non preferred embodiment, the width of the frame may be greater than its length. Preferably, the dimension in width is greater than or equal to the width of the ship 10. In an alternative embodiment, the dimension in width is less than or equal to the width of the attitude of the ship 10.

Advantageously, the frame can accommodate in its interior a canvas to have a sunshade effect or awning during the shipping of the ship. The canvas being removable, it can be removed when moving on a solid surface. In the embodiment where the width of the frame has a dimension less than or equal to the width of the ship 10, the connection between the structure 22 and the arm 21 is on a longitudinal portion of the frame (Figure 1 for example).

For all embodiments of the structure 22, the connection can be made inside the frame thanks to an additional connecting element. The additional connecting element may for example be a bar or a cross member. Advantageously, the presence of at least one cross member makes it possible to reinforce the rigidity of the frame. Thus, to stabilize the frame, a complementary support element can be positioned. In the embodiment of FIGS. 1 and 2, this complementary element is a piston positioned to balance the frame and preferably to form a triangle with the arm 21 and the structure 22.

In one embodiment of the invention, the connection between the structure 22 and the arm 21 allows pivoting of the structure 22 around the link. Thus, for example, the inclination of the structure 22 relative to the horizontal may be variable.

The structure can also, in an alternative embodiment have the form of a hoop. In this embodiment not shown in the figures, the length dimension of the structure 22 is smaller than the width dimension of said structure. The arch can be curved and / or rectilinear.

Advantageously, the structure 22 has a predominantly perpendicular position relative to the support arm 21. Thus, when the underrun device 20 is in its first position, the structure 22 has a predominantly vertical orientation. Conversely, when the underrun device 20 is in its second position, the structure 22 has a predominantly horizontal orientation.

The structure 22 may comprise at least one of the following additional elements: a canvas, a rod holder, a hook, a winch. These elements are not limiting, and other elements may be included and / or reported on the structure. These additional elements allow the structure 22 to have second varied functions, especially when the underrun device is in its second position. The hook for example can especially be used to set a rope for water sports such as water skiing or wakeboarding (wakeboarding).

Advantageously, a connection and an electrical wiring is present in and / or on the structure 22 and the arm 21. This electrical connection is of course sealed and makes it possible to link the signaling elements 25 with the console 12 and / or the towing vehicle during displacements on solid surface. Thus, this solution offers the advantage of limiting the immersion problems of the electrical connections. In addition, the connection vehicle / vessel can be done on a portion closer to the vehicle in particular to ensure its non-immersion when launching and the water outlet of the vessel 10.

Axis of rotation 23, function and use of underrun protection

The underrun device 20 has the first function to prevent pedestrians and / or two wheels pass under the wheels 40 of the ship 10 and / or the trailer in case of accident. Advantageously, the an-embedding device also comprises at least one secondary function.

The various functions of the underrun device 20 allow it in particular to adapt to both the displacement of the ship 10 on a solid surface in water. This adaptability according to the movement medium is achieved by the ability for the underrun device 20 to move from a first position to a second position. Preferably, the first position is below the second position.

The transition from the first position to the second position is advantageously by a rotational movement. In order to achieve this rotational movement, the shell 11 comprises an axis of rotation 23.

Advantageously, the axis of rotation 23 is parallel to the transverse axis of the ship 10. Preferably, the axis of rotation 23 is a geometric axis. That is to say that there is not necessarily a physical axis crossing the width of the ship 10. In this embodiment, rotary fasteners may be for example present on the shell 11 and on the axis of rotation 23 In another embodiment, the rotary fasteners are carried by the console 12 (see Figure 3 for example). The rotation of the underrun device 20 has the particular function of passing said underrun protection device 20 from a first position to a second position. Advantageously, the first position of the underrun device 20 corresponds to at least a first function, and the second position of the underrun device 20 corresponds to at least a second function.

The first function preferably corresponds to the antislip bar function. In this position, the structure 22 has at least one portion located at the hubs of the wheels of the trailer and / or the wheel 40. The purpose is to reduce the distance between the ground and the hull 11 to prevent that a pedestrian and / or a two-wheel does not pass under the wheels of the trailers and / or the wheel 40. Thus, in the first position, the structure 22 must have at least one portion at a distance of between 40 and 55 centimeters ( cm) of the ground and preferably 50 cm from the ground .. This preferred position allows in particular to have an intermediate element between the ground and the hull 11 preventing a pedestrian and / or a two wheels from passing under the wheels of the trailer and / or wheel 40 by lowering the guard.

The second function of the underrun device 20 is preferably a hood or sunshade function. Indeed, in the second position of the underrun device 20, the structure 22 at a predominantly horizontal position. Thus, thanks to a fabric filling the frame of the structure (preferred embodiment of the invention), the latter can realize a cover.

Thanks to this embodiment of the invention, that is to say to a ship 10 comprising a built-in underrun device 20, said ship 10 guarantees a secure surface movement for the surrounding people while limiting the disadvantages of the the presence of an underrun protection device 20. The reuse of this underrun protection device 20 saves the weight, bulk and enhance the overall safety of the ship.

The coupling device 30 is preferably located at the stern 14 of the shell 11. The coupling device 30 is rotatable about an axis of rotation 33 parallel to the width dimension of the shell 11. It can thus pass from a hitch position to a raised position. This can be substantially at 90 ° relative to the coupling position. The coupling device may be framed by the two beaches and / or comprise two spaced apart longitudinal members so as to form a clearance space around the engine. The hook may be fixed on a transverse part of the coupling device 30. The dispsoitif may be in two independent and tilting parts, at least one of which comprises the towing hook.

In hitching position, said coupling device 30 is in the extension of the bow axis 13 / stern 14 of the hull 11. In this position it allows the ship 10 to be towed by another vehicle.

In the raised position the coupling device 30 is maintained along an axis parallel to the first axis.

The hitch structure may include one or more bars. The bars can advantageously be telescopic. Thus, one can quickly and easily adjust the desired length is for the towing of the ship 11, or to avoid when navigating the water to raise the center of gravity of the ship 11. This improves in particular the stability of the ship 11. From moreover, the coupling device 30 may comprise a sliding cadenae (visible in FIGS. 1 and 2), in particular to assist the rotation of said coupling device 30, which further improves the safety of said ship.

In an alternative embodiment of the coupling device 30, visible in particular in FIGS. 3 to 5, said coupling device 30 does not include an axis of rotation. Nevertheless, the coupling device 30 is movable in translation inside the shell 11. This mobility is in particular allowed by a sheath 34 provided in the shell. Stoppers, not visible in the figures, make it possible to limit the movement of the hitching structure 32 with respect to the sheath 34. It is also possible to provide a length of the hitching structure 32 allowing the positioning of the hitching structure 32. several end stops in series to increase the safety when towing the ship 10. A leakproof hatch 35 allows, when the coupling device 30 is folded into the hull 11, to prevent water from entering in said shell 11. The hatch then opening to allow the retraction of the coupling device 30.

This realization has many advantages. By integrating the device inside the hull 11, the center of gravity of the ship 10 is lowered, which gives it a better stability. In addition, the hitch device 30 can add a mass to the bow 13 of the ship 10. In doing so, this can facilitate the planing of the vessel 10 at low speed and thus reduce fuel consumption. Finally, having no axis of rotation 33, the safety of the ship 10 is further increased during its towing by reducing the points of weakness of the coupling device 30.
